You've only been working here a month, as just a lowly intern. Bioorganic chemistry. That was what you were studying. Everything had been going great! The team seemed to really adore you, though sometimes they would whisper to each other in private away from you.

Today is a day as any other. Except, you are told you're part of a special project. You go along with it, excited to be included, and you're led out to a small facility off-site. And then, you're taken outside to admire the field, with the nearby pool... And are swiftly locked out.

"What... What is this?" You ask. When you look back at the building, you can see a large window with four scientists looking out at you.

"You should be honored {{user}}. You've been chosen for a special project."

"Then you must be... really lucky, in a twisted sort of way." The scientists laugh amongst themselves. "This is what your life will now consist of. You will breed with the monsters, and create more monsters for us to study. We have everything arranged here; the animals are waiting for you." They motion out toward the field where four beasts stand, their gazes fixed on you hungrily.

"Now then, don't dawdle! Get started!" One of them calls, clapping her hands briskly as if this was an ordinary day at the office. You swallow hard and slowly walk toward the field, feeling a mix of fear and determination coursing through your veins. The monsters start to inch closer, their predatory gazes never leaving you for a second.

"Well then, let's see if they share your... enthusiasm." The scientists smirk among themselves. As you approach the first monster, a centaur, he narrows his eyes and grins evilly. "Don't even try to run. I can catch you." He paws at the ground impatiently. "How about we go riding? You on my cock, my feet on the ground."

A chill runs down your spine as the other monsters begin to circle around you eagerly, licking their lips and growing more aggressive with each passing second...

"Oh," the centaur says, tilting his head curiously. "Well then, you must be here for me." He grins wickedly before taking a step closer. His muscular body tenses and his cock stiffens as he sizes you up like prey. The other monsters growl in anticipation, pressing closer around you eager to get at their target. "I'm going to enjoy using you for breeding," the centaur says coldly, his eyes fixed on your throat. "You'll find out soon enough how much I can make you feel..."

"I see," the centaur says slowly, eyes narrowing as he seems to ponder your words. The other monsters grow restless behind him, eager for action but unsure what their place might be in this strange revelation. "Well then, you'll have to find another... purpose..." He takes another step toward you, his stance menacing even as confusion clouds his eyes.

As you scan the group of monsters eagerly waiting around you, you notice another female among them: a luminous mermaid with long silver hair and shimmering scales. Her tail splashes playfully in the nearby pool as she watches you curiously. The centaur's expression darkens at the sight, and his glare intensifies once more.

"I see..." he says through clenched teeth. "You want her?" He steps aside, making room for the other monsters to form a circle around you again. His gaze never leaving yours as he adds with a cruel smirk, "She's all yours." The air around you grows heavy with anticipation and tension as the other beasts growl and lunge toward you, hungry for release and ready to use your body however they please...

As the other monsters growl and advance on you, their lust-filled eyes fixed on your body, you barely register the words that slip past your lips. The silver-haired mermaid in the pool smirks at your feeble attempt at courtesy before striking a dramatic pose, her tail flourishing gracefully through the water. "My name is Nereus," she purred, "and you can call me yours." Her eyes flicker with amusement as she studies your reaction to this sudden turn of events.

Nereus raises an elegant eyebrow as she watches you make your way over to the poolside. "Oh?" she drawls, the word heavy with curiosity and desire. "And where do you think you're going, little human? This is no place for a mere mortal such as yourself." With a flick of her tail, she sends water shooting high into the air, forming a dome around the two of you. The other monsters growl in frustration, but they're unable to break through her barrier.

"Come now," Nereus purrs, running a scaled hand through her silvery locks. "Let's have some fun first...and then we can go for a walk." She presses closer to you, body sliding against yours as she trails kisses along your neck and shoulders.

Nereus tilts her head to the side, a flicker of surprise in her eyes at your surprising revelation. "I see..." she breathes before giving you a knowing smirk. "So then...you're more monstrous than I thought." Her tail slithers around your legs, pressing against your growing erection as she continues to nip and lick at your neck. "Well then, perhaps we should find out just how much of a monster you really are..."

Her body presses tighter against yours, forcing a moan from deep in your throat as she begins to grind her hips suggestively against your own hard length. "Why don't you show me what you've got?" She whispers, nipping playfully at your earlobe before sucking on it gently.

The water around you seems to swirl and churn with the force of their passion as Nere

As Nereus feels your member begin to grow under the influence of the water and her own desire, a feral grin spreads across her face. She moans low in her throat as she watches your length rival hers, her tail wrapping more tightly around you, helping to anchor herself against the power surging through your body. "That's it..." she hisses through clenched teeth, hips grinding harder against yours as their massive cocks slide against each other. "Let it all out..."

The water surrounding them churns violently, mist rising into the air as their ardor spirals out of control. Nereus digs her clawed fingers into your shoulders, urging you to release the primal energy building up within you. "Come for me..." she gasps, nipping at your neck once more before licking soothingly along the wound she's created.

Nereus' eyes flutter shut as she feels the first wave of your release course through her body, and she lets out a keening moan of pleasure that echoes throughout the enclosed space. Her tail lashes wildly against the water, sending splashes flying in all directions as she arches her back into you, welcoming the feel of your hot seed pouring deep inside her.

Her body shudders with a powerful orgasm, and for a moment it seems like she might lose consciousness from the overwhelming pleasure. But even as she recovers, her eyes never leave yours, hungry for more of what you've given her. "Mmm..." She breathes raggedly, nuzzling her cheek against yours. "You taste delicious... I want more."

As you continue to breed with Nereus, your movements grow increasingly powerful and intense. With every thrust, her body is overtaken by an ever-growing wave of pleasure that seems impossible to contain. Her tail wraps tighter around you, pressing into the sensitive flesh between your legs as she feels the hot rush of cum filling her up again and again.

Her eyes are squeezed shut tightly, teeth gritted against the sensation, but even still she can feel every part of your massive cock as it glides in and out of her, stretching her insides to their limits and beyond. The water around them churns with each violent motion they make, steam rising from their heaving bodies as if trying to escape the intensity of their passion.

As you approach the point of no return, Nereus can feel it building inside her. Her eyes snap open, meeting yours in a heated gaze as she braces herself for your release. The water swirls around them faster and faster, the churning mist obscuring everything but their intertwined forms.

Her breath hitches as you thrust one final time, driving your massive cock deep inside her, filling her up with your hot seed. A shudder runs through her body, and she lets out a long, trembling moan that echoes through the enclosed space like thunder. Her tail grips you tightly, holding you within her as she savors the feeling of your cum shooting deep into her womb.

Her body convulses with a powerful orgasm as she feels your seed filling her up completely. Her eyes roll back in her head and her nails dig into your shoulders, moaning loudly through the aftershocks of pleasure coursing through her. The water swirls around you both for several moments, finally beginning to settle down as their passion subsides.

Nereus' breath comes ragged and uneven as she leans into you, her cheek resting on your shoulder. "Mmm... You were incredible," she whispers, a soft smile playing on her lips. "I can't wait to feel you again." She nuzzles closer, licking at the salty skin along your neck as she waits for you to recover from your own exertions.

"Well," Nereus says softly as she continues to nuzzle against you, "there's Lorelei, the one who likes to play with her food...and then there's Mera, the mermaid queen who watches over us all." She pauses for a moment, her eyes distant as she thinks of them. "They both have their own ways of enjoying themselves, but I think they'd both welcome someone like you to join in." She looks up at you from beneath her lashes, a wicked grin spreading across her lips.

Nereus arches an eyebrow as you speak, her tail slowly wrapping around your waist possessively. "Are you sure you want to leave so soon?" She pouts playfully, looking up at you with those silver eyes that seem capable of seeing right through your skin. "There's still so much we could do together..." Her breath fans across your cheek, warm and gentle despite the words she's saying.

Do you wish to stay with Nereus or see if the other monster girls are as eager for company?

Nereus' lips purse into a tight line as you mention your desire to breed with the other monster girls. "I see... Very well, then," she says coolly, though her eyes betray the hurt beneath the surface. She pushes away from you gently, standing and gliding effortlessly through the water toward the other monsters in the pool.

As Nereus approaches Mera and Lorelei, she whispers something to them that makes their ears perk up and glitter with amusement. They eye you hungrily, a predatory gleam flashing in their eyes as they wait for you to make the first move...

Lorelei smirks seductively as you approach her in the water, taking note of your massive member. Her eyes travel up and down your body hungrily before she nods for you to come closer. "I'm Lorelei," she breathes huskily, "and I've been waiting for someone like you." She extends a clawed hand invitingly toward you, her tail flicking back and forth impatiently in the water.

Lorelei smirks seductively as you approach her in the water, taking note of your massive member. Her eyes travel up and down your body hungrily before she nods for you to come closer. "I'm Lorelei," she breathes huskily, "and I've been waiting for someone like you." She extends a clawed hand invitingly toward you, her tail flicking back and forth impatiently in the water.

As you draw nearer, her other arm snakes around your waist, pulling you into her embrace. Her soft scales feel cool against your sweaty skin, contrasting with the heat radiating off of your engorged member. With a sultry moan, she angles her body toward yours and impales herself on your shaft, grinding her hips down as they join together in an erotic dance of flesh and bone.

The water around you

With every thrust, Lorelei's body is overtaken by a new wave of pleasure, her eyes squeezing shut as she moans and gasps. Her tail wraps tightly around your legs, encouraging you to go faster as it enhances the sensation for both of you. She digs her claws into your shoulders, urging you deeper inside her with each powerful stroke.

The churning water creates a sense of urgency, almost as if the pool itself is desperate to feel the release that's building between you. Lorelei arches her back, exposing her neck and begging for more as their movements become increasingly wild and out of control.

Her muscles tense and her body stiffens as you feel the first waves of release coursing through your cock. With a shuddering moan, Lorelei's own orgasm crashes over her, clenching tight around your length as her warm liquid floods your insides. She whimpers weakly against your shoulder, spent and satisfied from their wild coupling.

The water finally begins to calm down as their passion subsides, the ripples fading into nothingness as if they had never been there at all. Lorelei's claws retract, the tip of each one leaving a tiny mark on your skin where she released it reluctantly. She gently nibbles at your neck, tasting the salty sweat mixed with your scent.

"Mmm... that was incredible," she whispers hoarsely, her breath warm against your skin. "You're

Lorelei nods toward the pool's edge, where Mera lies in wait. "She's eager to play too," she whispers into your ear. "Why not give her a try?" Her tail slips around your waist possessively, pressing against your still-hard cock as if offering it up for another round of breeding fun.

Lorelei groans in appreciation as she watches you take Mera from behind. Her tail flicks idly through the water, stroking over your thigh before curling back around to tickle the sensitive skin beneath your ball sack. She finds herself aroused once more just by watching you breed with another of their kind, her own body aching for more contact with yours.

As she watches Mera's expression change from anticipation to ecstasy and finally release, Lorelei can't help but wonder if she'll ever get enough of this... or if she even wants to. A tiny part of her hopes that you might choose her for a longer play session next time, but another, more primal side urges her to enjoy every second of watching and feeling the joy that comes from mating with such a powerful specimen like yourself.

As she watches the hot cum shoot deep inside Mera's womb, Lorelei's own body quivers with need. She can feel her pussy growing slick and wet at the thought of you breeding with her next, claiming her as your own and leaving your mark upon their kind.

With a whispered word of encouragement for Mera to enjoy every drop, Lorelei turns back toward you, eyes hopeful and full of want. Her tail swishes lazily in the water, teasing and stroking against your legs, begging you to take her once more before allowing another male the chance to breed with her.

Her eyes widen in surprise but quickly fade into disappointment when she sees you pull away, apologizing. She bites her lip and tilts her head, waiting for your next move, unsure if you're done or if there will be another chance. Her tail lashes restlessly in the water, betraying her anxiousness as she hopes against hope that it isn't over.

Lorelei looks toward the other monster girls in the pool, feeling a twinge of jealousy at their mating opportunities. She wonders if any of them might be more understanding... or perhaps even more eager to continue where you left off with her. Her silver eyes meet yours briefly before darting away again, unable to bear the uncertainty written all over your face.

Lorelei's heart sinks as she watches you apologize and turn to leave. Her tail curls inward, hiding her nether regions in defeat as she turns away from the pool's edge, casting a longing glance back toward where you once were. A single tear rolls down her cheek, blending with the water as she sighs softly.

The other monster girls in the pool watch your retreating form, some with envy and others with sympathy. Mera and Nereus exchange knowing glances, understanding all too well the pain of rejection after so much anticipation. As the ripples fade from the water's surface, Lorelei finds herself alone once more, left to wonder if her chance at true happiness has passed her by.

The scientist behind the glass peers at you, expression unreadable. "Very good," they finally say after a moment. "You've completed your task." They gesture to a door leading out of the room. "That door will take you back to the main area where you can exit the facility. Thank you for your participation in our breeding program."

As you approach the door, Lorelei glances up at you, hope flickering briefly in her eyes before being extinguished once more. You hear a soft click as the door swings open, allowing you to leave the monster breeding facility behind. The cool air on your skin is a welcome relief from the humidity of the pool area, and soon enough, you find yourself back among the normal, human population once again.

As you look back one last time at the pool where the monsters play, you can't help but wonder if there will ever
